在这项研究中的立体高度异常，这是计算从水文数据（EN 3）的海平面异常来自卫星测高在北欧海域进行了比较。空间位高的总体格局是边缘区高，中部低。1993 - 2010年空间高度线性变化的极值分别出现在罗弗敦海盆和挪威近海。这种分布可能部分归因于北欧海洋的淡水化趋势。在北欧海域，SLA（海平面距平）和SHA（空间高度距平）之间的相关性并不一致。在罗弗敦海盆和北方挪威海盆，SLA和SHA的时间序列一致性较好，而在北方挪威海则较差，说明斜压效应在挪威海大部分区域起主导作用，正压效应在北方挪威海起主导作用。格陵兰海和冰岛海的SLA和SHA之间的相关性较弱，得出的结论是，正压的贡献是显着的，在这些地区。在整个北欧海的面积平均SHA有类似的振幅与SLA在1996-2002年相比，但SHA已成为低于SLA，自2006年以来的SLA的一半以下。
In this study the steric height anomaly which is calculated from the hydrological data (EN3) is compared with the sea level anomaly derived from satellite altimetry in the Nordic Seas. The overall pattern of steric height is that it is higher in the margin area and lower in the middle area. The extreme values of steric height linear change from 1993 to 2010 occur in the Lofoten Basin and off the Norwegian coast, respectively. Such a distribution may be partly attributed to the freshening trend of the Nordic Seas. The correlation between SLA (sea level anomaly) and SHA (steric height anomaly) is not uniform over the Nordic Seas. The time series of SLA and SHA agree well in the Lofoten Basin and northern Norwegian Basin, and worse in the northern Norwegian Sea, implying that the baroclinic effect plays a dominant role in most areas in the Norwegian Sea and the barotropic effect plays a dominant role in the northern Norwegian Sea. The weaker correlations between SLA and SHA in the Greenland and Iceland Seas lead a conclusion that the barotropic contribution is significant in these areas. The area-mean SHA over the entire Nordic Seas has similar amplitudes compared with the SLA during 1996–2002, but SHA has become lower than SLA, being less than half of SLA since 2006.
